💡 Pro Tip:
Enable “Extract Root Domain Only” to consolidate all subdomains under their parent domains. This is especially useful for SEO backlink analysis where you want to count links per root domain rather than per subdomain.
✨ Key Features & Options
1. Extract Root Domain Only
This option extracts the root domain from any URL, removing all subdomains. Perfect for SEO analysis when you need to count unique domains rather than subdomains.
| Input URL | Root Domain Output |
|---|---|
https://blog.example.com/post |
example.com |
https://www.subdomain.example.com |
example.com |
http://shop.example.co.uk/products |
example.co.uk |
2. Keep ‘www.’ in Results
By default, the tool removes www. from domain names. Enable this option if you want to preserve the www subdomain in your results.
3. Keep Protocol (http/https)
Enable this to preserve the protocol in the extracted results. Useful when you need to maintain the full URL format or differentiate between HTTP and HTTPS domains.
4. Remove Duplicates
Automatically eliminates duplicate domains from your results. Essential when processing large lists where the same domain appears multiple times with different URLs or paths.
5. Sort Results Alphabetically
Organizes extracted domains in alphabetical order (A to Z). Makes it easier to review and analyze your domain list, especially for large datasets.
6. Convert to Lowercase
Ensures all extracted domains are in lowercase. Recommended for consistency since domain names are case-insensitive but may appear in mixed case in URLs.

🛡️ Creating Google Disavow Files
What is a Disavow File?
A disavow file is a text file you can upload to Google Search Console to tell Google to ignore certain backlinks when assessing your site. This is useful for removing bad or spammy links that could harm your SEO.
How to Create a Disavow File
- Export Your Backlinks: Download your backlink report from Google Search Console or SEO tools like Ahrefs, SEMrush, or Moz
- Extract Domains: Use our tool to extract root domains from the URLs. Enable “Extract Root Domain Only” option
- Review Manually: Carefully review each domain. Only disavow links you’re certain are harmful
- Format for Google: Add
domain:prefix to each line (you can do this manually or with a text editor) - Upload to Google: Upload the file to Google Search Console’s Disavow Tool
⚠️ Important Warning:
Only use the disavow tool if you’re certain you have harmful links. Disavowing good backlinks can hurt your SEO. If you haven’t received a manual penalty notification from Google, you probably don’t need to disavow links. When in doubt, consult an SEO professional.
Disavow File Format
A properly formatted disavow file looks like this:
# Spammy domains to disavow
domain:spamsite1.com
domain:badlinks.net
domain:spammy-seo.org
# Individual URLs (use sparingly)
http://example.com/spam-page

Domain names are case-insensitive, but they may appear in different cases in URLs. Always convert to lowercase for consistency and to ensure proper duplicate detection.
4. Validate Results
After extraction, quickly review a sample of results to ensure the tool extracted domains correctly, especially if working with unusual TLDs or international domains.

Save your original URL list before extraction. This allows you to cross-reference results or re-process with different options if needed.
